Abstract

It is shown that the linear {sigma} model in one-loop order in the chiral limit recovers meson masses m{sub {pi}} = 0, m{sub {sigma}} = 2m{sub qk} (NJL), m{sub {rho}} = {radical}2 g{sub {rho}} f{sub {pi}} (KSRF), along with couplings g{sub {sigma}{pi}{pi}} = m{sup 2}{sub {sigma}}/2f{sub {pi}},g{sub {rho}{pi}{pi}} = g{sub {rho}} (VMD universality) and Weinberg`s mended chiral symmetry decay width relation {Gamma}{sub {sigma}} = (9/2){Gamma}{sub {rho}}. (author). 15 refs, 5 figs.
